CNN Says Recall for Engine Shields and Inspect Welds in Rear compartment

We all known about the "oil spill" fires. They will be modifing our engine shields. What I didn't know is that some cars may have "incomplete" welds in the rear compartments. Anybody heard of that before?

Recall letters will start going out from GM in July.

Actually, 3 weeks is pretty quick. Consider that GM needs to get the information and any required parts to their dealerships before the first owner calls in for the recall. I have seen up to six months from the time the recall was announced to the time the first notices were mailed.

What parts? From what I read they're just going to drill holes in the existing plastic shield to let oil drain out from sloppy oil changes. Not even gonna bother taking mine in for this unless there's some other reason to bring it in - then I'll have it done.
Since I don't know exactly what the change is, I can't say if parts will be required or not. In any event GM must provide instructions to their dealerships.
...the lower engine shrould (cover) is item #10 in this illustration:
Thanks for posting the link to this diagram. I just looked at it. I noticed that the engine plate alreay has huge open areas where hot liquids can drop through. I remember seeing an "after" photo in another thread yesterday and it simply appears they are making it wider and a little longer towards the front of the engine. It appears GM engineers had already considered this issue and simply went back to the drawing board to figure out the new cut size. Knowing how engineering design works, I wouldn't be surprised to learn that the "new" cut may actually have been a previously proposed design that wasn't selected.
From looking at the parts diagram on, it appears the catalytic converters are still above the modified engine plate.
Although no replacement parts are involved, I bet GM is sending a "cutting template" along with instructions to their dealerships. This would explain the three week delay in sending out bulk recall mailings. I definitely wouldn't want my dealership to cut the shield without a template to show where to cut.
According to GM, there are 61,000 cars that have the fuel tank assembly that came off the machine that missed the welds. However, only 249 of them actually have the missed welds. The problem is that GM doesn't know which 249 out of the 61,000 and this has more to do with the way modern assembly lines operate than anything else. The inspection for the missed welds is nothing more than looking at how the fuel tank is secured and take just a few seconds to do. Since they all need to come in for the splash shield modification this simply means the tech walks to the back of the car while it's up on the lift and look up to count welds.

Also, the cars missing the welds still meet US safety standards, just not GMs.

I'm not a GM employee. What I read was that the missing welds are visible (actually not visible in this case) with a undercarriage inspection of the gas tank mounts. The release I read said that bolts/fasteners will be used instead of welding the missing spots. I have no idea why GM chose to use bolts and fasteners for this repair.

As for the news reports, always, always, treat numbers as biased, even when they are factually correct. Reminds me of the old cold war joke about a race between a Ford and a Soviet built car. The Ford won handily, but Pravda reported "The people's car finished second while the capitalist car finished next to last" without reporting that it was a two car race. Automotive News should have reported that 61,000 Cruzes need to be inspected but that only 249 are expected to require repairs. Automotive News also didn't report that this repair is to a secondary tank securing strap that isn't required by the US Government.

I do try to keep what I repeat accurate to what I read. Sometimes I'm in error and will gladly have the correct information pointed out by someone else. These forums work best when we all try to get the most accurate information out.

Welding on the chassis is a "no-no".
That's what I suspected, especially with gas in the tank. I know autobody repair shops do weld to the chassis in some cases, but only after they basically take the car apart.
